Question

x³ - 16x⁵ (factorise)​

Answer 1

Sorry. I can only factorise numbers like 2, 3, 4, ....97, 98, 99.

Answer 2

$\sf{\red{\boxed{\bold{Solution}}}}$

⠀⠀⠀⠀

$\sf:\implies \: {\bold{ x^3 - 16x^5 }}$

⠀⠀⠀⠀

$\sf:\implies \: {\bold{ x^3 ( 1 - 16x^2) }}$

⠀⠀⠀⠀

$\sf:\implies \: {\bold{ x^3 ( 1^2 - (4x)^2) }}$

⠀⠀⠀⠀

$\sf{\orange{\boxed{\bold{a^2 - b^2 = ( a + b ) ( a - b)}}}}$

⠀⠀⠀⠀

$\sf:\implies \: {\bold{ x^3 ( 1 - 4x )( 1 + 4x ) }}$
